for specific human-desired features depletes natural populations of alleles which confer those desirable phenotypes. Often, these features (large horns, large size, specific pelts) are not only desirable to humans, but play roles in survival within the animal’s natural habitat and role within their ecosystem. By cutting down the number of animals bearing those desired phenotypes (and thus harboring the associated alleles), the amount of genetic material necessary for conferring those phenotypes upon later generations of the population is depleted (an example of genetic drift). This selection changes population structure over time, and can lead to a decrease in the wild-condition fitness of the population as it is forced to adapt around hunting-condition pressures. Impacts on tourists' perceptions and behaviours towards wildlife With the emergence of social media, many tourists have begun posting images online of themselves partaking in wildlife tourism experiences. These posts are not, in themselves, always negative, however they do often lead to increased visitation at wildlife tourism experiences, and can encourage behaviours that impact animal welfare. These behaviours, such as being too close to wildlife, can impact the behaviour, health, location and mating of some species. In addition, photos posted from animal tourism experiences can send unintentional message to viewers, particularly when a person is in the frame. For example, across a range of species, the presence of a human in a wildlife image can increase people's perceptions that the animal would make a good pet, or experiences negative welfare. In response to these impacts and animal welfare concerns, Instagram and other social media sites now display warnings when viewers search for terms such as "#wildlifeselfie". Positive impacts Habitat restoration by eco-lodges and other tourism operations Many owners of eco-accommodation or wildlife attractions preserve and restore native habitats on their properties. In a large way, the tourists and travelers visiting the wildlife destinations contribute to the conservation and improvement of the conditions for the animals. The flow of the people keeps the poachers at bay from killing the valuable animals. The local tribes have a decent living as the tourism flourishes as it provides opportunities of improved livelihood. Conservation breeding Many wildlife parks (e.g. David Fleay Wildlife Park, Gold Coast, Australia) and zoos breed rare and endangered species as a part of their activities, and release the progeny when possible into suitable habitat. Financial donations Some wildlife tourism contributes monetary donations to conservation efforts e.g. Dreamworld, Gold
